What Is an EIN Number?
An Employer Identification Number (EIN), also known as a Federal Tax Identification Number, is issued by the IRS to identify a business for tax purposes. It’s required for:
- Opening a business bank account
- Filing federal taxes
- Hiring employees
- Applying for business licenses and credit
Ways to Get a Copy of Your EIN Number
1. Check Your Original EIN Confirmation Letter (CP 575)
When you first applied for your EIN, the IRS sent you a confirmation letter (Form CP 575). Search your records for this document—it contains your EIN in bold at the top.
2. Check Past IRS Correspondence
If you’ve filed tax returns or received IRS notices, your EIN will be listed on those documents.
3. Look at Business Bank Account Records
Most banks require your EIN when opening a business account. Check your account setup documents or statements.
4. Contact the IRS Directly
If you still can’t find it, call the IRS Business & Specialty Tax Line:
- Phone: 800-829-4933
- Hours: Monday–Friday, 7 a.m.–7 p.m. local time
Note: Only authorized individuals (such as the owner or principal officer) can request this information.
Can I Get a Copy of My EIN Certificate Online?
No, the IRS does not provide EIN certificates (CP 575 letters) online. However, if you applied for your EIN online, you might have downloaded a PDF confirmation page—check your email or downloads folder.
